I've been working on this since the start of the year, but > been thinking about the problem for over 10 years. I've only been thinking about how this is done for very short periods of time. My naive approach to timestretching would be to transform the signal into the frequency domain [either by windowe fourier or by wavelet transform]. and then afterwards retransform, but with a changed time base. Actually i rather think of it as synthesizing the timestretched material from the frequency information.. I'm sure i miss something [haven't actually looked at the math [especially for the retransform with changed timebase] though i do have some fourier/wavelet transform knowledge] Florian Schmidt -- kT
